Agree "turned the season around" is a bit of an exaggeration, but your version gives the Sox several uncounted wins instead of losses. Is it 8? If so, that puts the Sox neck and neck with the Astros for 2d best record in the AL and--you're going to just love this--4 games behind the Yankees. If you convert 1 of the losses to the Yankees, the margin is 3 games.
I completely agree a closer has to start sometime, but would challenge you to find just one who started closing on the first day (or first closeable game) of a season. Last season was Whitlock's first ever in MLB. And, for the record, he had 2 saves and 3 blown saves without ever being a closer.
At the beginning of the season Barnes and Robles had the experience as closers. Indeed, in the first game of the season, April 8, Whitlock was a reliever who pitched 2.1 innings and gave up 1 run. The 9th inning pitcher was--wait for it--Robles, who pitched a scoreless 9th. Then Dieckman and Brasier gave up the 1 unearned run in the 10th and Crawford the winning unearned run in the 11.
In his very next game, April 12, Whitlock pitched 4 scoreless innings in relief and the Sox beat the Tigers. Three outings later, April 23, he pitched 4 more scoreless innings as the starter vs. the Rays, a game the Sox lost in the 10th when Robles gave up an unearned run after the Sox failed to score (with a man on 2b) in the top of the 10th.
Indeed, for the month of April Whitlock pitched 16.2 innings--against the Yankees, Twins, Jays, Rays, and Tigers--while giving up 1 earned run for an ERA of 0.54. The Sox won 3 of those 6 games, and could have won 2 others (3-2 to the Rays and 1-0 to the Jays) if the Sox hitting had been better.
And you claim that Cora the idiot misused Whitlock in April? Do you even look at actual facts before you sound off? No, you don't. You simply make stuff up.
