Waiver Worthy: Which Hot Adds Are Worth Grabbing (Mookie Betts, Jesse Hahn & More)

by Eric Stashin (aka The Rotoprofessor)

Let’s take a quick look at the most added players (according to CBS Sports as of Tuesday) to try and determine if they are worth adding or if fantasy owners should pass:


Mookie Betts – Boston Red Sox – Second Baseman/Outfielder
Add Percentage – 38%

Seeing Betts sit atop this list should surprise no one, as he is the most recent hot shot prospect to join the Major Leagues.  It’s hard not to get excited about his arrival, after he hit .345 with 8 HR, 48 RBI, 70 R and 29 SB in 304 AB between Double and Triple-A this season.  He is certainly a potential sparkplug, and also was nearly as impressive at two different levels of Single-A in ’13 (.314, 15 HR, 39 SB).

The most impressive part of his game is his command of the strike zone, with a 9.9% minor league strikeout rate and 13.6% walk rate.  That’s going to make him a potential OBP machine with the ability to steal bases.  That’s an awful lot to like, especially once he moves up in the lineup.

I’d consider Betts over Martin Prado, Austin Jackson (in other words a potential OF3/4 at this point)


Jesse Hahn – San Diego Padres – Starting Pitcher
Add Percentage – 37%

He has certainly made an impressive impact since being recalled, going 4-1 with a 1.95 ERA and 1.05 WHIP in 27.2 IP.  Interestingly, though, is that his pitching profile thus far doesn’t match what we would’ve expected from his minor league numbers.  His strikeouts have been huge (11.71 K/9 vs. 8.76 in minors), his control has been just decent (3.25 BB/9 vs. 2.65) and the groundballs haven’t been impressive (46.8% vs. 58.6%).  Unless those things, especially the groundballs, fall into line there could be a few rough days ahead (25.1% line drive rate, 85.1% strand rate, .274 BABIP).  He’s worth owning, but don’t be surprised if he soon starts to struggle.

I’d consider Hahn over Charlie Morton, R.A. Dickey


J.D. Martinez – Detroit Tigers – Outfielder
Add Percentage – 22%

Martinez continues to be one of the hotter adds, as he is making quite the impact.  That said, he also continues to own a dramatic split:

  • vs. RHP – .392/.409/.725
  • vs. LHP – .103/.205/.282

That’s going to keep him as a player that is a much better fit for those in daily formats.  Of course there are more RHP than LHP, so unless the Tigers have a slew of southpaws on the schedule he is going to be worth using while he’s hot.

I’d consider Martinez over Nick Markakis, Colby Rasmus (same as last week)


C.J. Cron – Los Angeles Angels – First Baseman
Add Percentage – 22%

With Raul Ibanez now in Kansas City, the DH job has been cleared for Cron.  Early on in his career he’s been impressive, hitting .290 with 8 HR, 22 RBI and 16 R over 131 AB.  The power number has been impressive, but fantasy owners need to be careful.  He currently owns a 26.7% HR/OFB, far greater than his 16.7% mark in the minors since ’11.  Yes, he was at 23.1% prior to his recall this season, but that also came in the PCL.

His calling card will likely be more his average than anything, so don’t buy him expecting massive power numbers.

I’d consider Cron over Kendrys Morales


Steve Pearce – Baltimore Orioles – First Baseman/Outfielder
Add Percentage – 20%

Pearce has been on a tear, hitting .327 with 9 HR and 25 RBI over 147 AB.  There is no doubt that he’s playing a bit over his head given a .379 BABIP (.297 for his career) and 18.0% HR/FB (8.7% for his career).  Obviously while he’s playing like this the AB will be there, but once he slows down they could quickly dry up.  He’s the type of player to ride while he’s going well, but not to get too attached to because he could easily become valueless before long.

I’d consider Pearce over Lucas Duda, Nick Swisher


Jarred Cosart – Houston Astros – Starting Pitcher
Add Percentage – 20%

He owns a 3.60 ERA and has shown tremendous groundball stuff (56.0%).  Is that really enough, though?  His strikeout rate is unimpressive, with a 5.87 K/9, and a 6.4% SwStr% doesn’t offer much hope for improvement.  His control is also questionable, with a 3.51 BB/9 this season and a 3.6 mark over his minor league career (4.7 at Triple-A).  There’s probably more risk than reward involved in picking him up.

I’d consider Cosart over Chris Young, Josh Collmenter
