Colorado Rockies trade rumors: relief pitcher edition

Left-handed reliever Tony Watson of the Pittsburgh Pirates is yet another potential target for the Rockies and we’ve mentioned him as a target before.
In 2017, Watson’s 4-2 with a 3.86 ERA and he’s had 10 saves. However, he has blown seven saves this season. He blew five saves in 2016 as well but he still had a good ERA of 3.06 in 70 games.
If he were to be acquired by Colorado, he would serve in a set-up role and he is best in that role. He spent 2014 and 2015 in that role as his average between those two seasons was a 1.74 ERA in 78 games and only 15 earned runs.
In Coors Field, his opponent’s have a batting average of .235 and an on-base percentage of .278 in eight appearances and pitched in nine innings. In that span, he’s only allowed eight hits and two runs at Coors.
In postseason play, Watson has appeared in five games and five innings and he has also four hits and one run for an ERA of 1.80.
He’s owed about $1.1 million for the rest of the 2017 season. He’s owed $5.6 million in 2018 and after the season, he will become a free agent.
David Robertson has pitched very well for the Chicago White Sox this season and he’s yet another person who we’ve discussed before.
In 29 games, he has a 2.87 ERA with 13 saves. He’s had a fantastic strikeout to walk ratio of more than four to one (13.2 to 3.2). He’s never had an ERA above 3.47 since 2010 and he’s never had an ERA higher than 3.82 in a full season in his career. He’s also not had a season in the past three with less than 34 saves.
In his career at Coors Field, which is four games and 3 2/3 innings and he’s only allowed one hit and he’s not allowed a run. His opponent’s have only hit .083, with a .283 on-base percentage, and a .167 slugging percentage.
He would bring a decent amount of postseason experience to Denver as he has pitched in 19 postseason games and he’s allowed 15 hits and seven runs in 17 innings of work, good enough for an ERA of 3.71.
He is owed a little bit less than $6 million for the rest of the season. He’s owed $13 million next season before becoming a free agent.
