Boston Red Sox prospect watch: Marcelo Mayer erupts

Red Sox Single-A (Salem)

Miguel Bleis had a tough week, but there were some positives. Those positives included five steals. The right-handed hitting outfielder is slashing .247/.300/.351 with three doubles, two triples, and one home run. He's driven in 14 runs, scored 16 more, and stolen 11 bases. Bleis has a lot of strikeouts (32), but he's 19 and perhaps a little too patient at the moment.

Luis Ravelo continues to show an impressive bat. The switch-hitting shortstop is slashing .275/.372/.388 with three doubles and two home runs. He's driven in 15 runs, scored 14 more, and stolen four bases. Ravelo's known mainly for his defense (and made some great plays this week). So the offense has been a nice surprise.

Cutter Coffey holds a .212/.409/.258 slash line with three doubles. The right-handed hitting shortstop has driven in four runs, scored 14 more, and stolen six bases. He's walked more times (21) than he's struck out (18).

Roman Anthony had a monster three-hit game on Sunday that included two doubles and three RBI. The left-handed hitting outfielder is slashing .221/.378/.294 with five doubles. He's driven in nine runs, scored 12 more, and stolen seven bases. Anthony has 17 walks compared to 18 strikeouts.

Yorberto Mejicano is slashing .393/.452/.571 with five doubles. The right-handed hitting catcher/first baseman has driven in three runs, scored five more, and stolen one base. Mejicano made some phenomenal defensive plays at first base this week and has caught three-of-seven base stealers as a catcher. He needs more playing time.

Ronald Rosario is slashing .250/.389/.429 with five doubles, one triple, and one home run. The right-handed hitting catcher has driven in 11 runs and scored 10 more.

Juan Chacon slumped a bit this week and is slashing .209/.386/.313 with one double and three triples this season. The right-handed hitting outfielder has driven in nine runs, scored 10 more, and stolen nine bases. Even with a struggling bat, though, Chacon continues to dazzle defensively.

Lyonell James had a big week, collecting hits in all four games and going 6-for-17 (.353) with a walk, an RBI, and two runs scored. The right-handed hitting infielder is slashing .243/.321/.311 with two doubles and one home run. He's driven in 13 runs, scored 12 more, and stolen two bases.

Karson Simas is slashing .238/.365/.286 with one triple. The right-handed hitter has driven in five runs, scored five more, and stolen three bases. Simas plays all over the field and made some nice plays at second base this week.

Allan Castro is in a deep slump and slashing .184/.349/.276 with five doubles and one home run. The switch-hitting outfielder has driven in 13 runs, scored 15 more, and stolen six bases. In his first 14 at-bats, Castro had seven hits (two doubles and a home run) and seven RBI. It's been tough since then. Castro's had some good swings, has 20 walks compared to 20 strikeouts, and is 19. Don't panic.

Ryan Zeferjahn was activated this week and is rehabbing in Single-A. The right-handed pitcher has thrown three scoreless innings over two outings. He gave up three hits and no walks, striking out two batters.

Jose Ramirez gave up two runs (neither earned) on two hits and three walks over five innings this week, striking out six batters. The right-handed pitcher has a 0.50 ERA, .123 BAA, and 0.83 WHIP in 18 innings. He's struck out 18 batters and walked eight.

Noah Dean had his best start of the season. The left-handed pitcher tossed five shutout innings, earning his first win. Dean has a 5.27 ERA, .213 BAA, and 2.12 WHIP in 13 2/3 innings. He's walked 19 batters and stuck out 23.

Elmer Rodriguez-Cruz went five innings for the second start in a row. The righty has a 2.03 ERA, .226 BAA, and 1.50 WHIP in 13 1/3 innings. He's struck out seven batters and walked eight. Five walks came in his first start of the year (three innings), though.

Felix Cepeda gave up two runs (one earned) in one inning in his first appearance this season. The right-handed reliever hasn't allowed another run since then (10 1/3 innings). Cepeda has a 0.79 ERA, .214 BAA, and 1.50 WHIP in 11 1/3 innings. He's struck out 11 batters and walked eight.

Luis De La Rosa has a 3.00 ERA, .197 BAA, and 1.22 WHIP in 18 innings. The right-handed pitcher has 17 strikeouts compared to nine walks, and he's yet to surrender a home run.

Dalton Rogers has a 3.55 ERA, .146 BAA, and 1.18 WHIP in 12 2/3 innings. The left-handed pitcher has struck out 25 batters compared to eight walks and has yet to give up a homer.
