Isiah Kiner-Falefa, Second Base
Another major league acquisition at the trade deadline was super utility man Isiah Kiner-Falefa. Despite getting hurt, Kiner-Falefa is having a career year at the plate, which is exactly what Pittsburgh needs. He will primarily be at second base for the time being until Nick Gonzales returns from injury.
This season with the Blue Jays, Kiner-Falefa has career highs in wRC+, batting average, on-base percentage, slugging percentage, OPS, and strikeout percentage.
Along with that, he is one home run shy of a career high with seven. In the past, he has stolen 20+ bases in a season, but he only has three this year. That is definitely something the Pirates could try to encourage, but for now it remains something up his sleeve.
His ability to play multiple positions effectively makes him very valuable, as there are many ways to get him in the lineup.
Joey Bart, Catcher
One of Ben Cherington's best trade acquisitions has been Joey Bart and, when healthy, he has been one of the best hitters on this team. He has performed so well at the plate that he's entered the lineup almost every day, aside from when Yasmani Grandal catches Paul Skenes.
This season, Bart has an impressive .825 OPS with seven home runs and 24 runs driven in. His .475 slugging percentage matches with a .350 on-base percentage to create his great OPS. Bart also has a very impressive wRC+ of 130 and his walk percentage is at 10.7%.
Bart is not a qualified hitter for any statistical rankings, but has a very strong hard hit rate of 44.7% and 74.9 mile per hour bat speed, which would both be ranked very highly across the league.
Getting a conistent hitting catcher in Bart is just what the Pirates needed, with struggles from Grandal and Henry Davis. Not only has his offense been great, but his ability to catch runners stealing has also stood out.
