DETROIT -- The Tigers made their first batch of official signings on Draft picks Tuesday, and it was a big batch. Detroit finalized deals with 24 selections, including its top three and six of its top 10.

Many of the early-round deals had already been reported, including top pick Derek Hill, second-rounder Spencer Turnbull and third-rounder Grayson Greiner. Several other deals were just announced Tuesday, including Kansas City outfielder Ross Kivett (sixth round), South Carolina third baseman Joey Pankake (seventh) and Dallas Baptist right-hander Paul Voelker (10th).

Among the four unsigned picks in the top 10 rounds, three of them are pitchers playing in the College World Series: Vanderbilt's Adam Ravenelle (fourth round), Virginia's Artie Lewicki (eighth) and Mississippi closer Josh Laxer (ninth). The other, fifth-round pick Shane Zeile, has been finishing his exams at UCLA.
