Links: Jeff Locke to make next start, Kevin Krause to have Tommy John surgery

A few notes for Tuesday:

-P- Jeff Locke will make his next start on Saturday. As disappointing as he's been lately, that's not too surprising. I would probably swap him and Vance Worley, but I think it's a close decision, and I can understand wanting to give Locke another opportunity or two before doing that.

-P- Catcher Kevin Krause, the Pirates' ninth-round pick last season, will have Tommy John surgery, Pirates Prospects reports (subscription-only). Since he's a position player, he should have a somewhat faster recovery time than is typical for Tommy John patients, putting him back on track for Spring Training next year. Still, this is a bummer -- Krause will be out for the whole season. He had a terrific debut at Jamestown last year, but by next year, he'll be 23 and without any experience in full-season ball.

-P- The Rays have designated old friend (is "friend" the right word?) Ernesto Frieri for assignment. Frieri's velocity and strikeout rate got him a big-league deal last offseason even after he completely flamed out in 2014, but his control problems and homer-allowing tendencies continued into the 2015 season.

-P- Keith Law ranks his top 100 draft prospects (Insider-only). This isn't a mock draft, so there isn't any Pirate-specific stuff in there, but if you've got an Insider subscription, it's a really useful guide. As usual, Law isn't afraid to go his own way with his rankings, so some players ranked in the 15-25 range, where the Pirates will have their first pick, typically go much earlier or later in most mock drafts. Ian Happ, who one mock draft recently sent to the Pirates, falls at No. 7; Daz Cameron is at No. 12 and Mike Nikorak is No. 22.
