Not a Bad Problem to Have

Name the Toronto Blue Jays starter by his stats over the last 30 days (slash line is ERA/FIP/SIERA because we fancy):

1. 37 IP, 3.23 K/BB, .303 BABIP, 66.0 % strand rate, 4.62/3.26/2.97
   
2. 22 IP, 3.00 K/BB, .341 BABIP, 72.3 % strand rate, 4.76/3.61/4.23
   
3. 37 IP, 3.00 K/BB, .259 BABIP, 88.5 % strand rate, 2.19/3.83/3.83
   
4. 33 IP, 2.00 K/BB, .265 BABIP, 72.9 % strang rate, 3.82/3.84/3.54

Who's your ace? Who's your number one? Who is the big second half guy and who just fixed his mechanics? NO CHEATING!

Make with the wild guesses in the comments, if you please.

THE RESULTS ARE IN!

Morrow, Carlos V, Cecil, and Ricky Romero.

Watch the unsustainables, Mr. Cecil! Keep being Brandon Morrow, Brandon Morrow. Ricky Romero is, always and forever, Ricky Romero.

The whiff rate breaks down just as you expect for these four pitchers, too. Morrow (11.8%), Romero (10.2%), Cecil (9.2%), and Villanueva (6.9%). League average is 8.5%. Carlos Villanueva, your pumpkinhood awaits.
