Free Agent Faceoff: K-Rod vs. Soriano vs. Janssen

Among the remaining free agents on the open market, only three held down a ninth-inning job for a significant portion of the season: Francisco Rodriguez, Rafael Soriano and Casey Janssen. The trio is similar in that each has a history of pitching in the ninth inning, each is in his mid-30s and each succeeds despite lacking an overpowering heater. Let’s take a bit of a closer look at each.

Rodriguez’s relative youth may surprise some; he’ll turn 33 in January. It may feel like he should be in his upper 30s, but that comes with the territory when you cut your teeth as a 20-year-old in the midst of a World Series run. K-Rod’s ERA has been 3.04 or lower in four of the past five seasons (a 4.38 in 2012 being the lone exception), and it has, in fact, been 3.04 or better in all but two of his 13 big league seasons. fWAR was down on K-Rod quite a bit this season, as his FIP of 4.50 was rather pedestrian. However, that number doesn’t account for his eye-popping 23.3 percent homer-to-flyball ratio. Rodriguez’s career mark in that field is 9.9 percent, and even if he’s more homer-prone now (and the past three seasons suggest he might be), it can be reasonably expected for his HR/FB to drop by as much as 10 percentage points. xFIP normalizes HR/FB when projecting a 2.91 ERA for Rodriguez, and even if the true talent level is something a bit higher, Rodriguez would have value. He’s the youngest of the three relievers in question and also had the best ground-ball rate (43.9 percent) in 2014.

Soriano is the elder statesman of this group at the age of 35. He, too, has just one ERA blemish under his belt over the past five seasons — a 4.12 mark in an injury-shortened season with the 2011 Yankees. Over the past three seasons he has a 2.84 ERA with 8.2 K/9 and 2.8 BB/9. Soriano throws the hardest of this bunch (91.5 mph average fastball in 2014) and was having far and away the best season of the group as of mid-August. Soriano’s ERA was under 2.00 entering play on Aug. 15, but he limped to the finish line, allowing 12 runs in 14 2/3 innings over his final 16 games. While that offers cause for concern, some clubs may just write it off as poor luck (he did have a .367 BABIP in that stretch).

Janssen, who turned 33 in September, was in the midst of a characteristically strong season when he caught a violent case of food poisoning. He reportedly lost eight pounds within a day’s time and was never fully recovered, which was a contributing factor to his 6.46 second-half ERA. Even when Janssen was healthy, his K/9 rate was down this season, however, and he does throw the slowest of this trio. However, Janssen has also shown the best command of this group in recent seasons, and he’s missed plenty of bats in previous years. Plus, his recent trials have come in the AL East, whereas Soriano and Rodriguez have both worked in the National League in recent years.

All three of these relievers could help a bullpen, but it doesn’t seem that all three will end up with a closer’s job. Clearly, this post is just a mere glimpse into each reliever’s profile, so feel free to do a bit more of your own research before answering…
