The Rangers signed their 21st round pick RH HS pitcher Luke Lanphere to a 400k deal per Jim Callis. So Texas dipped in to its 328K taxable overage to cover this. They have about 130K left if they haven't already used it on someone.
BA ranked him in the top 500 at 491:
Lanphere generated top-10-rounds buzz down the stretch this spring, but most scouts think that's too rich. He tickles 91 mph now and then early in games but pitches in the 80s, and his breaking ball and changeup are well below-average. His best asset is the projection remaining in his 6-foot-4, 175-pound frame, and he could boost his stock significantly if his velocity jumps and his secondary stuff improves at UC Riverside.
Texas also signed undrafted FA catcher Brett Teschner (6.3/235, 8/23/91) and assigned him to the AZL. He played at Division 1 Lipscomb in 2009-2010 (part-time? - 24g) but might have been out of baseball since then. Check that. Looks like he was injured in 2011 (12g) and then transferred to Division 2 Columbus State for JR/SR campaign, where he played in 50+ games each year (h/t Ming). Probably looking at a 1b/DH type.
