Draft Signings: Evans, Armstrong, Horstman

Here are today's most notable signings from Day 2 and Day 3 of the draft (slot information courtesy of Baseball America)…

• The Royals signed fourth round draft pick Zane Evans, Baseball America's Jim Callis tweets.  Evans signed for $400K, below the $450.4K assigned slot value for the 114th overall pick.  Evans was both a catcher and a right-handed relief pitcher at Georgia Tech and Callis believes Kansas City will use him as a catcher.
• The Reds have signed third-rounder Mark Armstrong, Callis reports (via Twitter).  Armstrong, a high school right-hander who had committed to Pitt, signed for exactly his assigned slot value of $496K.
• The Mariners have signed St. John's left-hander Ryan Horstman, Callis reports (via Twitter).  Horstman, one of the few college freshmen eligible for the draft, was taken in the fourth round by the M's and signed for $550K, a significant bump up from his slotted price of $437.6K.
• Junior college right-hander Kenyan Middleton tweeted that he has officially signed with the Angels earlier today. Middleton, the No. 95 overall pick, is advised by Tripper Johnson of Sosnick & Cobbe. His slot carries an assigned pick value of $541K.
• The Cardinals signed third-rounder Mike Mayers for a little more than a $500K bonus — about $58K below his assigned pick value — according to Rick Hummel of the St. Louis Post-Dispatch. Mayers is a right-hander out of Ole Miss.
• Baseball America's Jim Callis tweets that the Phillies signed fourth-rounder Jake Sweaney for $400K. Sweaney's deal is $21K below slot. The high school catcher was committed to Oregon and has a plus arm with power potential in his bat.
• The Twins signed third-rounder Stuart Turner for a $550K bonus that is well below the No. 78 pick's assigned value of $703K, Callis tweets. The Mississipi backstop was regarded as the best catch-and-throw college catcher in this year's draft, and Callis notes that he had a strong year at the plate too.
• Ben Nicholson-Smith of Sportsnet.ca reports that the Cardinals have agreed to an over-slot deal with 10th-rounder Malik Collymore. The Canadian high school second baseman will receive a $275K signing bonus, which is significantly larger than the recommended $135K.
• Eleventh-round selection Spencer Navin also received a significantly over-slot deal, tweets Callis. The Dodgers gave the Vanderbilt backstop $300K — three times the $100K maximum for draft picks after the 10th round. Players drafted after the 10th round don't count toward a team's bonus pool as long as they sign for $100K or less. In other words, the $200K excess to sign Navin will count against the Dodgers' draft pool.
• The Astros have signed fourth-round pick Conrad Gregor for a bonus of $482K, tweets Callis. The Vanderbilt first baseman has good patience and athleticism but has yet to tap into his power, Callis adds. Gregor signed for full slot value.
