May 12, 2015 - 4:35 am

In the middle number of their three-game series against the A's on Tuesday night, Red Sox right-hander Justin Masterson will get the ball at the Coliseum opposite left-hander Drew Pomeranz. Masterson's last outing was forgettable as he lasted 4 1/3 innings against the Rays last Wednesday, walking six and giving up four earned runs on seven hits with one strikeout. Masterson said he felt something change part of the way into the fourth inning. He was over-rotating a little bit in his pitching motion. "The first part was great, first three innings," Masterson said Wednesday. "The fourth, pitched through it, and fifth was just kind of the culmination of I just couldn't make the adjustment out there to get back into throwing strikes. Close, but not close enough. "I just felt like I was rotating more," he added. "Which is never a good thing, when I'm already a rotational guy, to add more rotation to it is not good, but it's something I hadn't dealt with yet this year, so at least we're not repeating what we've been doing." With a 5.18 ERA and a 2-1 record six starts into the year, Masterson has allowed 19 earned runs in 33 innings of work, giving up 34 hits in that time. He has issued 18 walks and struck out 23. Hitters are slashing .268/.377/.409 against him, and he has a 1.58 WHIP on the year. In 10 starts vs. the A's, Masterson has an ERA of 6.61 with a 2-7 record. Among teams he's faced more than twice, Masterson has only fared worse in those categories against Tampa Bay. In 62 2/3 frames, Masterson has surrendered 66 hits, 28 for extra bases, and 46 earned runs. A's batters have a .269/.358/.461 slash line when he's on the hill, and his 1.53 WHIP is his fourth worst against teams he's seen at least five times. Pomeranz has never recorded a start against the Red Sox, but he's faced them on two occasions, once in 2014 and once in 2013, for a total of 3 1/3 innings and a 2.70 ERA. In that time, the lefty has given up just one earned run with a walk and four strikeouts. Boston has batted .231/.286/.231 with him hurling, just three singles in 13 at-bats, and he's registered a 1.20 WHIP. Pomeranz has made six starts for Oakland this season, pitching 31 2/3 innings with 18 earned runs and 27 strikeouts for an ERA of 5.12. Owning a 1-3 record, he has a WHIP of 1.39 with 33 hits, 12 for extra bases, and an opponent slash line of .264/.321/.432. He most recently pitched against the Twins on Thursday, lasting, similar to Masterson, 4 1/3 innings. Pomeranz also gave up four earned runs like his Red Sox counterpart and walked five in the outing. The biggest difference between the pair's starts is that Masterson allowed the damage on seven hits total, while Pomeranz did so on three.
