In a win over the Chicago White Sox on April 4, 2017, Verlander tied a franchise record for the most strikeouts on Opening Day with ten, becoming the first Tigers player to do so since Mickey Lolich in 1970. In his 51st plate appearance in interleague play, Verlander recorded his first career RBI in an August 30 game against the Colorado Rockies which was also his last game as a Tiger.
After a couple of injury-riddled seasons, many believed Verlander had lost the fastball velocity to which most fans had grown accustomed. However, his velocity soared back up to an average of 95.3 in his 2017 campaign, four miles per hour faster than his average in 2014 (91.2), and three MPH faster than his average in 2015 (92.3). He also hit triple digits on the radar gun in 2017 for the first time since his 2013 season.
For the 2017 postseason, Verlander made six appearances and five starts, being credited with a 4–1 record, and gaining a 2.21 ERA, .177 batting average against, eight walks, and 38 strikeouts in 36 ⁄3 innings. Along with Jose Altuve, Verlander was also named winner of the Babe Ruth Award as co-MVPs of the 2017 postseason.
On August 16, Verlander struck out 11 batters over 7 innings against the Oakland A's. It was his sixth consecutive start with 10+ strikeouts, setting an Astros franchise record and becoming the first pitcher to achieve this since Max Scherzer and Chris Sale in 2017. In combination with his prior start against the Baltimore Orioles on August 11, Verlander now has more strikeouts than innings pitched in his career.
Verlander throws four pitches: a hard four-seam fastball averaging 94–95 mph (topping out at 102), a slider in the mid-to-high 80s, a 12–6 curveball around 80, and a changeup at 85–88 mph. His four-seam fastball has an "elite" spin rate of over 2500 rpm according to Statcast, giving it a late "tailing" action that cuts inside to righties and away from lefties. He often uses his four-seam fastball up in the zone to hitters. This has allowed him to strike out more batters with that pitch than any others. His slider has evolved throughout his career. In his early years, his slider was in the mid-80s with a larger break. However, in recent years, Verlander has added velocity to his slider. This change has caused a later, sharper break that has led many to believe it is actually a cutter, although Verlander has denied this on various occasions. In 2017, Verlander began to incorporate both sliders. He usually throws the slower, longer slider under the hands of lefties, and the sharper, faster slider down and away to righties. His 12–6 curveball has always been a dominant pitch that buckles hitters' knees at any point in the count. He also intentionally uses this pitch up in the zone at times to freeze hitters or throw off their timing. Since the 2016 season, Verlander has essentially become a three-pitch pitcher (fastball, slider, curveball). His changeup has been used almost exclusively against left-handed batters in recent years, and its usage has dropped considerably. The changeup accounted for 8.5 percent of his pitches in 2016, only 4 percent of his pitches in 2017, and less than 2 percent of his pitches in 2018.
Verlander is known for his unusual ability to "add" and "subtract" from his fastball velocity at any point in the game, giving him the ability to throw it in the upper 90s even in the late innings of games. Since 2008, Verlander has thrown pitches of over 100+ mph in the 8th inning or later 44 times, 39 more times than James Paxton who is second on the list. This is despite the fact that he has thrown the most pitches in the major leagues since the beginning of the 2008 season. After a couple of injury prone seasons, many believed Verlander had lost the velocity most fans had grown accustomed to. However, Verlander's velocity soared back up to an average of 95.3 in his 2017 campaign, 4 miles per hour faster than his average in 2014 (91.2), and 3 MPH faster than his average in 2015 (92.3). Verlander's average fastball velocity with no strikes is 94.7 mph, while with two strikes it is 97.0 mph.

His life experiences and the story of his development are outlined in his parents' 2012 book, Rocks Across the Pond: Lessons Learned, Stories Told. His younger brother, Ben played for the Tigers organization as an outfielder. Ben was released on June 23, 2017.
