MLB Draft 2016: Top college pitchers fail to build upon previous week's performances

Here's you're weekly MLB Draft update, set to track some top prospects that the Colorado Rockies might be in the mix to draft this June. In this week's updates... struggles. Lots and lots of struggles.

Florida lefty A.J. Puk

Punk had trouble keeping the ball in the strike zone against Harvard on Saturday, walking four in 5⅓ innings. He allowed just one run on one hit while striking out three batters on 84 pitches (50 for strikes).

In the sixth inning, Puk got a grounder to third base for the first out of the inning, but it turned out to be the last one he recorded. He walked the next batter before being pulled from the game. Reliever Brady Singer allowed the inherited runner to score on a passed ball and a single to right field.

Season line: 4 GS, 0-1 W-L, 2.65 ERA, 17 IP, 10/5 R/ER, 18 K, 9 BB

Related: RHP Logan Shore (No. 21 on Baseball America's latest top 100 draft prospects list) saw his 17⅓ scoreless inning streak go to 18⅓ on Friday against Harvard, but he finished the game with five runs allowed over six innings while striking out six. The Gators' offense put up 15 runs, though, for the win.

Alec Hansen, RHP, Oklahoma

Hansen failed to follow up on last week's strong start, opening the game against Long Beach State by surrendering two runs on two hits, two walks, a single and a bunt. The Dirtbags stole four bases in the first frame, though the last two came after the runs scored.

Hansen allowed two more runs in the third inning and one in the fourth. He didn't get the hook after that, but it wasn't long in coming. The Colorado native put down the first two batters in the fifth inning before he issued a four-pitch walk to the third.

Final line: 4⅔ IP, 5 H, 5/4 R/ER, 5 K, 4 BB, 92 pitches
Season line: 4 GS, 0-3 W-L, 6.00 ERA, 15 IP, 12/10 R/ER, 22K, 12 BB

Matt Krook, LHP, Oregon

Oregon didn't have it going against Mississippi State at all over the weekend, and Matt Krook was no exception. The lefty started the game decently by allowing a single, striking out a batter, allowing a single, and striking out a batter. Then he lost all sense of the strike zone, throwing a wild pitch and walking three straight batters. By the time the leadoff batter was in the box again, Krook gave up four runs. He was pulled during that at-bat and saw his reliever issue a walk for another run.

Final line: ⅔IP, 2 H, 5 R/ER, 2 K, 5 BB, 41 pitches

Others of note

Kyle Lewis, OF, Mercer: Lewis went 3-for-4 with a solo homer and two RBI on Saturday before unleashing a two-run shot in a loss on Sunday. He also an RBI walk in the rubber match. His slash line is .444/.563/.873 (28-for-63) with six doubles, seven home runs, and 22 RBI.

Connor Jones, RHP, Virginia: Jones opened ACC play for the Cavaliers with eight shutout innings and three strikeouts against Duke. He now has a 1.98 ERA over 27⅓ innings, He has struck out 24 while allowing 24 hits and walking six.
