In [three starts in June], Lester allowed 17 runs in just 15-1/3 innings of work, while striking out 14 batters against 10 walks. Six of his 18 homers on the year came in just those three games -- his home run rate the rest of the year looks very similar to that of Lester at his peak. Again, we're not scrubbing them from the record, but Lester packed together a significant portion of his awfulness into one teeny stretch -- 23 percent of the runs he's allowed all season came in these three contests.
So, while Lester hasn't had a complete return to his dominant past, he's still been a highly reliable piece in the Red Sox rotation. Even with those three poor starts on his record, he has a 103 ERA+ and 4.09 ERA, and is on pace for over 200 innings for the fifth time since he became a full-time starter back in 2008 -- those innings are significant by themselves, as a look back to last year reminds: only 31 starters logged at least 200 innings, out of the 150 starting slots available around the league, and of the 286 pitchers who started a game. Even if Lester were only average when all is said and done, there's huge value in that volume of average.Lester used to be an ace. He's not anymore, but he's still settling into performing as an above average pitcher - when he's not losing control of his mechanics like he did during those three awful starts in June. We just need to recalibrate our expectations of him.
