In a season plagued by injuries and inconsistent offensive production, utility man Andruw Monasterio has emerged as one of the Red Sox’s most productive hitters. After starting the season 2-for-14 and drawing attention for a viral ABS challenge, Monasterio found his footing in the team’s April 25 matchup against the Baltimore Orioles. He went 3-for-6 with his first career grand slam, marking a turning point in his offensive production. But despite his breakout at the plate, defensive struggles continue to keep him from securing an everyday role. Acquired from the Milwaukee Brewers in the six-player trade that featured Boston acquiring Caleb Durbin, Monasterio was added to the roster as a depth piece but has taken advantage of his limited opportunities. His versatility has allowed the Red Sox to deploy him across the infield, with Monasterio appearing at first base, second base, shortstop and third base this season.. Quietly, he has produced a 100 wRC+, at least 30 points higher than every current Red Sox starting infield outside of first baseman Willson Contreras. In 66 at-bats, he is batting .258/.310/.424 with a .734 OPS, and his underlying metrics suggest there could still be room for further growth. He owns a .288 expected batting average and a .423 expected slugging percentage, while his .335 xwOBA ranks fifth on the team. His average exit velocity has climbed to a career-high 90.8 mph and his 46.9% hard-hit rate is also the highest mark of his career, tantalizing proof that he’s consistently making better contact than ever before. A significant part of his improvement is in his approach against fastballs, which he is hitting .282 this season, a .057 increase from last year. However, despite his revelation at the plate, his fielding is what’s keeping him from being an everyday starter. While his offensive numbers are positive, his defense has led him to -0.1 fWAR. This is in large part due to his having a -3 outs above average across all of his positions, the lowest on the team. Statistically, he only converts 67% of fieldable balls, while his expected success rate is 82%. Monasterio has struggled most at shortstop, where he has a -2 out above average. He has completed only 60% of plays, while his estimated success rate is as high as 82%. This inefficiency is why he continues to be third on the depth chart at shortstop, behind Trevor Story and Isiah Kiner-Falefa, despite both having wRC+ figures below 50. This whole equation could change drastically now that Story is headed for the injured list. Nick Sogard was called up from the minor leagues to serve as a utility depth option, but he's not an everyday starter. And you can be sure that Kiner-Falefa won't be getting more than the occasional rep at shortstop given his complete lack of offensive competence. Can the Red Sox live with a slightly worse glove at the most important infield position if it means getting Monasterio's bat in the lineup with regularity? The Red Sox are not in a position to be picky, as they currently sit last in the American League East and rank among the bottom six in the MLB with a .239 expected batting average. In their series opener against the Atlanta Braves, Monasterio drew the start at shortstop over Story, showing the team is willing to prioritize his bat despite his defensive limitations. If he can maintain his offensive production while showing improvement in the field, he could continue to carve out a larger role and potentially emerge as a longer-term option in the infield.

Carlos Narváez was expected to serve as a placeholder for the Boston Red Sox after catcher Connor Wong fractured his pinky finger last season. Acquired from the New York Yankees for minor-league pitcher Elmer Rodriguez-Cruz, Narváez emerged as a defensive specialist and a solid bat in the lineup. Last season, the rookie backstop hit .241/.306/.419 with a .726 OPS, eventually taking the starting role from Wong in the process. However, in his first season as the primary option, Narváez has struggled to replicate his production from his breakout year, starting 2026 by hitting .234/.265/.277, good for a .542 OPS. Due to his lack of offensive production, Narváez has produced a -0.4 bWAR and a 49 wRC+, leading to a move to the ninth spot in the lineup. While his defensive value still ranks toward the top of the league, Wong has had his own strong start to the season and puts more pressure on Narváez each day to figure out his swing. So, what going on? To put it simply: Narvaez's regression can be tied to his struggles against fastballs. Against fastballs this season, Narváez has produced -3 run value (zero is average) with a .192 wOBA, all while whiffing at one in every four he swings at. His batting average and slugging percentage against fastballs sit at just .172 each, a drop off from his expected figures of .221 and .358. With fastballs accounting for nearly 60% of the pitches he sees, Narváez needs to figure out a way to fix his approach immediately. However, the issue may not be mechanical, but rather related to timing and the contact point. This season, his average launch angle has dropped from 13.2 degrees to 6.9, indicating a downward trend in his swing path. That observation is supported by a sharp increase in his topped-ball rate, which has risen from 29.1% to 35.3%, along with a decrease in balls that he gets underneath (falling from 26.7% to 14.3%). Narváez has yet to record a single pull-side ball in the air against fastballs, further indicating he is failing to hit the ball out front. Instead, his batted-ball distribution suggests that he is consistently letting pitches travel too deep. Nevertheless, the Red Sox can take some relief in knowing Narváez’s underlying tools haven’t disappeared. While much of his offensive profile has declined, he still ranks among the league's top percentiles in average exit velocity and hard-hit rate. This data backs the claim that his raw abilities haven’t diminished, but rather they are being watered down by poor timing, leading to hard contact at unfavorable launch angles. Although his production against fastballs has been poor, he has been producing against off-speed pitching, though those results may be due to a bit of good luck rather than a better approach. As it stands, Narváez's delayed timing at the plate is limiting his ability to execute against the pitch he sees the most, even as it occasionally puts him in better positions against off-speed options. The tools are still there, but the margin for error is shrinking. If Narváez can make the necessary timing adjustments against fastballs, his production should follow. If not, pitchers will continue to exploit the gap. View full article

Amid a slow start for the Boston Red Sox, veteran first baseman Wilson Contreras has emerged as an unlikely hero while the majority of the lineup struggles at the plate. In a recent series win against his former team, the St. Louis Cardinals, Contreras continued his strong start, going 4-for-5 with a home run and three RBIs. In his 11th season, he is batting .304/.443/.500 with a .943 OPS. Touted as an underrated pickup after Boston acquired him in a trade from the Cardinals, Contreras has lived up to the hype, ranking second on the team with a 171 wRC+ while playing stellar defense. “There’s a reason we got him. We needed another right-handed bat, and we got more than that. We got a guy that is playing great defense at first base, he controls the strike zone, he’s becoming a leader in the clubhouse. It’s fun to have him around,” Red Sox manager Alex Cora said about Contreras' contributions thus far. Soon to be 34 years old and coming off a few down years with the Cardinals, Contreras' renaissance at the plate seems to be driven by his improved plate discipline. Known throughout his career for producing high hard-hit rates, the veteran slugger has actually taken a dip in that regard this season. His hard-hit rate sits at only 42.1%, down from his career-high 48.9% from last year. However, this shouldn’t be perceived as a slight on him, but an example of his change of philosophy at the plate. Although his overall contact quality isn't at peak levels, his slugging percentage and xSLG have spiked up to .500 and .517, compared to last season's .447 and .488. A lot of that jump can be tracked to his newfound affinity for left field (and the Green Monster); Contreras is pulling the ball at a career-high 54.1% rate, while his contact to center field has dropped to a career-low 24.3% and his opposite-field rate sits at 21.6%, the second lowest of his career. This marks a major contrast to last season, where his spray chart featured a much more balanced split, 39.4%/37.1%/23.5%. Notably, the last time he had as big a gap in his spray chart was in 2022, when his split was 44.4%/31.7%/23.8%. Coincidentally, that was also the last time he made an All-Star team. Contreras’ selectivity at the plate has extended to every aspect of his game. This season, his swing percentage is at a career low, 41.1%, and he's being very patient, swinging at a near-career-low 25.5% pitches outside of the strike zone. Ultimately, what’s helping his decision-making is that he is also finding himself in very advantageous early counts. This season, his first strike percentage is at 44.8%, an almost 15% drop from his previous career low of 58.7% in 2019. These early count advantages, combined with his laying off "pitcher's pitches" outside the zone, are forcing a few more predictable options around the plate, which he has been capitalizing on. While the sample size is small, Contreras' adjustments are exactly what the Red Sox have needed from their biggest offensive acquisition. Hopefully, his patience will start to carry over to the rest of the team. View full article
