Prospect Roundup: Games of May 11

White Sox SS Tim Anderson, Triple-A Charlotte: 3-for-5, 2B, RBI, 3 R -- This is the Tim Anderson we came to know at other levels. The White Sox's No. 2 prospect, who hit over .300 in each of his two previous Minor League seasons, had a .220 average as late as May 6. But after Wednesday's showing in Charlotte's 7-4 win at Norfolk, the 22-year-old shortstop is 10-for-25 (.400) with two doubles, three RBIs and seven runs scored in his last six games with the Knights, pushing his season slash line up to .256/.279/.296. Four of his games during that run have featured multiple hits, after he had put together only five multi-hit performances in his first 23 contests. As that line shows, the power isn't at all there for Anderson, even by his standards, and because he hasn't reached base at a high rate either, his six steals are below expectations for a player with a 70-grade run tool. But both the player and the organization will take the positives as they come, and with Anderson collecting hits in bunches again, a positive is certainly here.

Brewers LHP Josh Hader, Double-A Biloxi: 6 IP, 4 H, 1 R, 1 ER, 1 BB, 6 K -- There's not much left for Hader to prove at the Double-A level. The Brewers' No. 4 prospect is yet to give up more than one earned run in any of his seven starts and has struck out a Double-A-best 46 batters over 34 2/3 innings. He's also become more efficient, having pitched six innings in two of his last three starts (despite never going over 89 pitches) after failing to hit that mark in his first four outings. The 22-year-old continues to be devastating against fellow left-handers as he's held them to a .042 average. In fact, Jacksonville's Peter Mooney was the first lefty to get a hit off Hader all season when he singled Wednesday night. Though many have thought Hader's future is in the bullpen, he continues to prove his potential as a starter and should be tested with a move to Triple-A Colorado Springs in short order.

Indians LHP Justus Sheffield, Class A Advanced Lynchburg: 6 IP, 6 H, 1 R, 1 ER, 1 BB, 7 K -- A good test for pitchers in the Carolina League these days is to see how they can handle a stellar Salem lineup. Sheffield passed that test Wednesday with his second quality start of the season. The southpaw also established a season high for strikeouts in his six frames. Two of them came against top Red Sox prospect and switch hitter Yoan Moncada, who is struggling against left-handers with a .192 average in 2016. Sheffield, who turns 20 on Friday, became the latest prospect to enter MLB.com's top 100 after Jon Gray graduated earlier this month, and he has backed that up with a 3.28 ERA and 33 punchouts in 35 2/3 innings for the Hillcats. Given his age, Sheffield is likely ticketed to stay with Lynchburg for the duration of the summer to continue his development.

Reds RHP Keury Mella, Class A Advanced Daytona: 8 IP, 7 H, 2 R, 2 ER, 0 BB, 8 K -- The longest outing of Mella's Minor League career could be what finally pushes him over the Class A Advanced hump. The Reds returned their No. 6 prospect, acquired from the Giants in last year's deal for Mike Leake, to the Florida State League and saw him struggle with efficiency in the early going as he failed to reach the sixth inning in his first four starts while averaging 5.6 walks per nine innings. He's been much better in that aspect of late with three straight quality starts and a Wednesday outing that saw a zero in the walks column for the first time in 2016. After 103 innings at Class A Advanced in 2015, the 22-year-old right-hander is a candidate to move quickly to Double-A Pensacola as soon as he's shown he has outgrown Daytona. It looks like that time could be soon.

Brewers 3B Jake Gatewood, Class A Wisconsin: 2-for-3, 2 HR, 3 RBI, 2 R -- As was the case with most of his offensive game, Gatewood's plus power was missing in the first month of the season as he failed to go deep in 81 April at-bats. May has been a horse of a different color. Gatewood went deep twice in the opener of a doublehader Wednesday for his second multi-homer performance in three games, giving him five long balls over 36 at-bats in May. Although he went 0-for-3 in the second contest of the twinbill, he still has a .417/.432/.889 line with five homers, two doubles and 14 RBIs in 10 games this month. No other Class A hitter has more homers or a higher slugging percentage this month than Gatewood. The 20-year-old is still fanning in 31.1 percent of his plate appearances and has walked just once in 119 times at the plate, but he was drafted for his power and is starting to make plenty good on that tool.
