Red Sox Double-A (Portland)
Ceddanne Rafaela is one of the hottest hitters in the Red Sox system. I'll be surprised if I'm still writing about him in the Double-A section for anything past July 1. The right-handed hitting centerfield is slashing .297/.337/.435 with 17 doubles and five home runs. He's driven in 35 runs, scored 39 more, and stolen 30 (seriously) bases.
Nathan Hickey is having no issues in Double-A. The left-handed hitting catcher already has six home runs in 83 at-bats at the level. Hickey is slashing .291/.377/.563 with nine doubles, one triple, and 10 home runs between High-A and Double-A. He's driven in 26 runs, scored 28 more, and stolen one base. Hickey also threw a runner out on Sunday.
Marcelo Mayer has had some bad luck in Double-A. He's not striking out at a bad rate, and he's had a lot of hard outs. But the left-handed hitting shortstop is only slashing .161/.229/.355 at the level. He does have three home runs, including a mammoth shot. Mayer is slashing .251/.325/.473 with 13 doubles, one triple, and 10 home runs between High-A and Double-A. He's driven in 42 runs, scored 31 more, and stolen eight bases.
Nick Yorke is slashing .278/.375/.463 with 10 doubles, three triples, and eight home runs. The right-handed hitting second baseman has driven in 31 runs, scored 45 more, and stolen six bases. Yorke is having a fantastic bounce-back season at the plate, and his defense has been spectacular.
Chase Meidroth has a .310/.459/.456 slash line with seven doubles and six home runs between High-A and Double-A. The right-handed hitting second baseman/third baseman has driven in 31 runs, scored 35 more, and stolen seven bases. He's walked 42 times and only struck out 39.
Niko Kavadas has a .224/.398/.460 slash line with five doubles and 12 home runs. The left-handed hitting first baseman has driven in 36 runs, scored 28 more, and stolen one base. His average and strikeouts (88) are issues, but the power and OBP are major bright spots.
Corey Rosier doesn't seem to slump for long. The left-handed hitting outfielder is slashing .309/.356/.444 with 12 doubles, two triples, and two home runs. He's driven in 18 runs, scored 28 more, and stolen 26 bases.
Phillip Sikes had a solid week and has bumped his slash line to .247/.327/.366 with 13 doubles, two triples, and two home runs. The right-handed hitting outfielder has driven in 20 runs, scored 32 more, and stolen 25 bases.
Luis Guerrero has a 1.32 ERA, .161 BAA, and 1.17 WHIP in 27 1/3 innings. The right-handed reliever has struck out 23 batters and walked 17 in 27 1/3 innings, picking up 11 saves. Guerrero likely won't be in Portland much longer.
Ryan Zeferjahn has a 3.00 ERA, .177 BAA, and 1.33 WHIP in 18 innings between Single-A and Double-A. The righty reliever has 29 strikeouts compared to just 13 walks. Zeferjahn is working his way back from injury and putting together his best season while doing so.
Brian Van Belle has a 2.70 ERA, .237 BAA, and 1.17 WHIP in 70 innings. The right-handed starter has 57 strikeouts compared to just 22 walks. BVB allowed just one run on four hits over six innings this week, another fantastic start. He's 3-0 in June.
Grant Gambrell has a 3.06 ERA, .186 BAA, and 1.08 WHIP in 32 1/3 innings in Double-A. The righty starter has 29 strikeouts compared to 13 walks. Gambrell has been impressive since getting promoted, and even when he struggles, he tends to give the team a chance to win.
Robert Kwiatkowski made his Double-A debut on Sunday and was pretty impressive. The right-handed reliever allowed one run on one hit and no walks over 2 2/3 innings of relief. He struck out one batter in that time.
Christopher Troye has settled down in Double-A. The right-handed reliever tossed three innings of work over two appearances this week. Troye allowed no runs on two hits and no walks while striking out five batters. He's down to a 9.00 ERA, .200 BAA, and 2.50 WHIP in six innings for Portland. The numbers are improving quickly.
