A’s Acquire Conor Jackson | FanGraphs Fantasy Baseball
"Demel, meanwhile, is expected to join a wretched D-Backs pen that ranks dead last in xFIP (5.16) and Win Probability Added (-6.88). A third-round pick in the 2007 draft out of TCU, Demel has missed lots of lumber as a pro (10 K/9) but has usually struggled to locate (4.5 BB/9). While the righty didn’t crack BA’s list of top 30 A’s prospects heading into 2010, Demel has added a cut fastball to his low-90’s fastball, changeup and erratic slider. In 28.2 IP with Triple-A Sacramento, the 24-year-old had 8.8 K/9, 2.8 BB/9 and a characteristically strong ground ball rate (49.4%; his overall GB% in the minors is 54.5). Demel’s worth monitoring, particularly if Arizona shops Chad Qualls to a team that focuses more on his very good track record and 3.56 xFIP this season instead of his bloated ERA."
