Los Angeles Dodgers ace Clayton Kershaw will start for the MLB World Series champions on Opening Day.

Dodgers manager Dave Roberts announced on Sunday that Kershaw will be on the mound when the team open their 2021 season against the Colorado Rockies on April 1.

It will be Kershaw's ninth Opening Day start – the most in franchise history – after a back injury prevented him from beginning the 2020 campaign.

Kershaw got the nod in a star-studded bullpen, including Walker Buehler and high-profile recruit Trevor Bauer, who is the reigning National League (NL) Cy Young winner.

"There's really no wrong decision," Roberts said. "I just feel that he's earned it, he's the right guy for the spot for 2021 -- for every reason I just think it makes the most sense."

The 32-year-old Kershaw – entering the final season of his three-year, $93million deal – helped guide the Dodgers to their first World Series triumph since 1988 last season.

During the coronavirus-shortened 2020 campaign, eight-time All-Star and 2014 NL MVP Kershaw had a 2.16 ERA with 62 strikeouts and eight home runs allowed.

In the playoffs, Kershaw's ERA was 2.93 with 37 strikeouts and four wins in five appearances.

The Dodgers will open their title defence away to the Rockies at Coors Field.

Kershaw is 11-5 with a 4.44 ERA when pitching at Coors Field, while the three-time NL Cy Young Award winner owns a 24-8 career record against the Rockies, including a 3.22 ERA.

The St Louis Cardinals made a splash after acquiring Nolan Arenado on Monday.

It cost five players, but the Cardinals fleeced the Colorado Rockies to bring in a five-time All-Star via a blockbuster trade.

The Cardinals will reportedly receive $50million in cash considerations, new deferrals in Arenado's contract that has six years and $199m remaining, and the waiving of his no-trade clause.

Arenado only signed an eight-year, $260m contract with the Rockies prior to the 2019 MLB season but Colorado opted to make a deal with the Cardinals.

The 29-year-old's arrival is a significant addition and quickly establishes the Cardinals as the team to beat in the National League (NL) Central ahead of the Chicago Cubs, Cincinnati Reds, Milwaukee Brewers and Pittsburgh Pirates.

St Louis – eyeing their first World Series championship since 2011 – now boast a formidable corner-infield combination in Arenado and six-time All-Star Paul Goldschmidt.

Arenado's a genuine star

The third baseman's record speaks for itself.

Eight Gold Gloves, four Silver Slugger awards and four Platinum Gloves, to go with three NL home run and NL RBI leader honours.

Arenado is one of two players in MLB history to win a Gold Glove in each of his first eight seasons in the majors, along with former Seattle Mariners favourite Ichiro Suzuki.

While he was hampered by a shoulder injury during the coronavirus-shortened 2020 season – tallying 46 hits, 23 runs, eight homers and 26 RBIs in 182 at-bats for the Rockies, Arenado was coming off a career-best .315 with 41 home runs and 118 RBIs in 2019.

Arenado had five successive seasons with at least 35 home runs and 110 RBIs from 2015-19 (before the shortened 2020 season) – tied for the longest streak in NL history, alongside ex-Cubs star Sammy Sosa (1997-2001).

The Cardinals, on the other hand, have never had a third baseman hit 35-plus home runs in a season in their history.

St Louis are one of five current franchises that have never had a third baseman hit 35-plus homers in a season (34 in 1992 and 2004), and they are the oldest team (1882) in that group, ahead of the Boston Red Sox (1901), Washington Nationals (1969), Mariners (1977) and Miami Marlins (1993).

After making his debut with the Rockies in 2013, Arenado has amassed 1,206 hits, 649 runs, 235 homers and 760 RBIs at an average of .293 in his career.

Since his first MLB appearance almost eight years ago, only Nelson Cruz (287), Mike Trout (267) and Edwin Encarnacion (265) have hit more homers than Arenado.

Arenado, though, tops the list for most RBIs since 2013 – ahead of new team-mate Goldschmidt (720), who sits fourth.

In the postseason, Arenado has two runs, one homer and three RBIs while averaging .190 in 21 at-bats.

The Cardinals – beaten in the Wild Card Round last season – lost to the Nationals in the 2019 National League Championship Series (NLCS), while they went down to the Red Sox in the 2013 World Series.

The St Louis Cardinals have acquired five-time MLB All-Star Nolan Arenado in a blockbuster trade with the Colorado Rockies.

St Louis and Colorado announced the deal on Monday, with the Cardinals sending Austin Gomber, Elehuris Montero, Tony Locey, Mateo Gil and Jake Sommers to the Rockies in exchange for Arenado and cash considerations.

The Cardinals will reportedly receive $50million in cash, new deferrals in Arenado's contract that has six years and $199m remaining, and the waiving of his no-trade clause.

Arenado signed an eight-year, $260m contract with the Rockies prior to the 2019 season but Colorado opted to deal the eight-time Gold Glove Award winner.

The 29-year-old was hampered by soreness in the AC joint of his left shoulder during the coronavirus-shortened 2020 season, tallying 46 hits, 23 runs, eight homers and 26 RBIs in 182 at-bats for the Rockies – who missed the playoffs.

Arenado was coming off a career-best .315 with 41 home runs and 118 RBIs in 2019.

A Gold Glove winner in each of his eight seasons in Colorado, where he made his debut in 2013, Arenado has amassed 1,206 hits, 649 runs, 235 homers and 760 RBIs at an average of .293 in his career.

In the postseason, the four-time Silver Slugger and four-time Platinum Glove winner has two runs, one homer and three RBIs while averaging .190 in 21 at-bats.

The Cardinals, who lost in the Wild Card Round last season, quickly become favourites to win the National League (NL) Central, which consists of the Chicago Cubs, Cincinnati Reds, Milwaukee Brewers and Pittsburgh Pirates.

Not since 2011 have the Cardinals won the World Series.
