Salvador Perez (C - KC) - Perez hit his sixth home run in just over 120 at bats and is now hitting .317/.341/.512. The backstop never showed much power in the minors or in his call-up last season, but he is still just 22 and catchers typically develop later. Although he doesn't walk much, he's shown an excellent ability to hit for average as he's hit a ton of line drives in two abbreviated seasons. He's an outstanding option against left-handed pitching and should be owned in well more than a third of the leagues he currently is.
Alex Cobb (SP - TB) - Cobb was excellent against the Blue Jays, allowing just one run on five hits in seven innings as he walked one and fanned seven. It was a good matchup against a right-hand heavy lineup in a pitchers' park for the righty who came into the game with a 3.66 xFIP and he took full advantage of it. The 24-year old hasn't posted big strikeout rates in the big leagues after doing so in the minors, but he combines solid control and strong groundball tendencies. He's an excellent option Monday in Seattle and should be owned in a ton more leagues than the handful he currently is.
Cody Ross (OF - BOS) - Ross hit his 17th home run of the year as part of a three-hit day with a walk. He is now hitting .277/.345/.534. He continues to rake both at Fenway Park and against left-handed pitching, as he has a massive gap in those splits compared to on the road and against right-handers. He's an excellent option against southpaws at home and a solid one against righties at Fenway and lefties on the road, making him a very valuable commodity.
Adrian Gonzalez (1B - BOS) - Gonzalez had three hits, all doubles, in five at bats to raise his line to .310/.353/.465. It appears his problems early in the season were due to playing out of position in right field, as he hit .386/.417/.548 coming into the day since moving back to first base. The walks and home runs are still mysteriously absent, but he's hit a career high amount of line drives. He's an excellent option at Fenway Park and a decent one outside it.
Kendrys Morales (1B, OF - LAA) - Morales hit his 13th and 14th home runs as part of a three-hit game to raise his line to .279/.325/.448. He is hitting a career-high amount of line drives which has led to a .329 BABIP, but his strikeout rate has increased significantly in his first full season since 2009. It isn't a result of simply seeing more pitches, as his walk rate has remained stable at a poor 5.8%. Not only has swinging at more pitches outside the zone boosted his strikeout rate, but it has also put him in pitchers' counts and in turn being unable to put the ball in play with authority, as his .169 ISO is the lowest since his first call-up in 2006.
