Chicago Cubs: There is still plenty left in the tank for the 30-year-old
Dickerson as mentioned earlier is coming off an injury-shortened season. With the Pirates and Phillies combined he played in 78 games and slashed .304/.341/.565 with 12 homers, 28 doubles, a .906 OPS, a 127 wRC+ and was a 1.0 fWAR player. Those 28 doubles in 78 certainly can raise some eyebrows.
Back in 2017 he was an All-Star with the Tampa Bay Rays, hitting a career-high 27 homers and slashing .282/.325/.490 with a 2.6 fWAR. He put up a career-high 2.8 fWAR back in 2014 with Colorado and won a Gold Glove with the Pirates in 2018. Overall he is a career .286/.328/.504 hitter with 115 homers, .832 OPS, 117 wRC+ and 11.5 fWAR in 776 games.
Take this as you will, Castellanos is a career .277/.326/.471 hitter with 120 homers and 10.4 fWAR in 888 games.
Dickerson has been a very productive hitter in his career. No he is not a walk machine, but he will get his hits and get a good number of extra-base hits. Not a leadoff guy but definitely someone who can set the table in the two-spot or bat down in the five/six spot. He is a lefty batter who has seen success against right-handers (career .290/.333/.533) and respectable numbers against southpaws, as well (career .272/.310/.409).
All told, he is a nice balanced player. Can make solid contact when needed, hit for some pop, trustworthy glove in the outfield and face both lefties and righties.
