Yesterday was the deadline to tender a contract to arbitration eligible players which means we saw 56 new players become free agents. Among those is several players that could be of value to the Cubs in 2021.
1. Archie Bradley, RHP
The veteran reliever was non-tendered despite posting a 2.95 ERA (3.67 xFIP) in 16 appearances and 18.1 innings pitched, he did make $4 million in 2020 and was due for a raise so it's possible the Reds just felt like he wouldn't have been worth the salary. It's worth nothing he posted his lowest strikeout rate since 2016 striking out 24.7 percent of hitters, but he also posted the best walk rate of his career walking just 4.1 percent of hitters. One concern is that he allowed an obscenely high line drive rate in 2020, with 35.3 percent of batted balls being considered line drives, and combined with a sharp drop in his groundball rate could suggest bad results in the future if the trend continues.
He did see a drop in his velocity as his fastball went from averaging 95.5 MPH in 2019 to 94.2 in 2020, but despite that is was actually a more effective with hitters slugging .325 with a .275 wOBA average compared to .459 and .349 respectively. The concern would lie in his curveball which went from 82.1 MPH to 80 MPH on the dot and saw some concerning results. The swing-and-miss rate in the pitch was almost halved which means hitters were making contact which the pitch at a much higher rate, it was still an effective pitch as hitters posted a .238 wOBA average, but that is something to pay attention to.
Just 28 he is likely to command a lot of interest in the free agent market, he has been one of the more effective relievers over the past few years with a 2.95 ERA in 152 ERA+ in 221 games since the start of the 2017 season. I'm not sure if the Cubs are going to be willing to pay the salary he will likely command, but he would go a long way towards providing some stability towards the back of the pen.
2. Eddie Rosario, OF
The non-tender of Kyle Schwarber created a hole in the Cubs outfield, and it's one that could potentially be filled by the Twins cast-off. The 29-year old outfielder hit .257/.316/.476 in 231 plate appearances for the Twins. He didn't show much in the hit tool or plate discipline department, but he did show very good power that would somewhat make up for the absence of Schwarber.
Rosario, however, is a butcher in the field so he would likely be reduced to a designated hitter if that rule sticks in the National League in 2021 (which seems unlikely). In 2019 he was worth -18 outs above average in left field, which could be an anomaly considering he posted -2 in 2018 and was a positive +2 in 2017, in the small sample size of 2020 he was worth -1, so obviously he isn't going to win any Gold Gloves, but it's also possible that 2019 was just a fluke and he realistically isn't that bad.
He's would not fully be able to replace the production of Schwarber, especially since his career walk rate is a Javy Baez-esque 4.7 percent, but his ability to drive the ball makes him potentially a very solid addition to a Cubs lineup that ranked just 9th in home runs and just lost one of their best sluggers.
3. Carlos Rodon, LHP
The former 3rd overall pick in 2014 has struggled to establish himself for the White Sox, and it's possible a change of scenery or even a move to the bullpen could work wonders for the southpaw.
Rodon has struggled with arm injuries having had Tommy John surgery in 2019 and he missed over a month in 2020 with a shoulder issue. When he was on the mound he wasn't very effective, in 11 appearances (9 starts) combined from 2019-20 he posted an uninspiring 5.74 ERA allowing 27 earned runs in 42.1 innings pitched, he did show good strikeout numbers with 52 punchouts and his 3.85 FIP suggests that maybe he was a little unfortunate in his results.
His fastball velocity has dipped significantly from it's peak of 94.2 MPH in 2016 to just 92.8 MPH in 2020, it's possible that it's just because he's working his way back from injury, or whether the injuries have impacted his velocity that much. He's just a three pitcher pitcher with a four-seam fastball, slider, and changeup combo, he has thrown a sinker in the past but threw in just three times in 2019 and not once in 2020. If the velocity drop is permanent he could be effective in the bullpen as he might be able to get a slight bump in velocity since he won't be expected to throw 90+ pitches an appearance.
He has had past success as a big league starter, and we all know the Cubs need pitching depth. He isn't likely to be very expensive due to his struggled the past two seasons combined with questions about his health and whether his arm will be able to stand the rigors of a full big league season
