The deal, which was announced Monday, involves multiple players and required Segura to waive his no-trade clause to join Philadelphia.

The Mariners' next trade after completing a big seven-player swap with the New York Mets is another blockbuster with a National League East team.
The blockbuster trade that will send Robinson Cano and Edwin Diaz from the Mariners to the Mets is likely going to become official Monday. He immediately solidifies the Phillies infield with his solid defense and excellent bat.
In 586 at-bats, Segura only had 69 strikeouts and 32 walks but had an impressive batting average of.303 with RISP (runners in scoring position). He is a two-time All-Star and led the National League in hits in 2016.
With all due respect to J.P. Crawford since the potential always seemed to be there, the addition of Segura would clearly be an upgrade at the position. Doing so could cost them well over $600 million, though Philadelphia has plenty of money to spend with less than $70 million committed to players for next season before landing Segura.
In an Instagram post, Crawford thanked the Phillies organization and Phillies fans for "the inspiration to work as hard as I do, day in and day out". He has struggled in 72 Major League Baseball games over two seasons, however, hitting just.214 with a.333 on-base percentage, .358 slugging percentage, three home runs and three stolen bases. Of his 1,080 swings, 527 were put in play, giving him the ninth-best contact rate at 48.8 percent.
Neither the 23-year-old Crawford nor Santana, signed to a three-year, $60 million deal last December, performed to expectations in their time as Phillies. He hit the go-ahead 3 run home run for the NL in the All-Star game off Josh Hader. But Santana did not do a good job of bringing runners home as he hit.229 with RISP. "He gets on base, he does damage at the plate and is quite an underrated first baseman".
